(a) Relative amplitude versus relative distance from the fixed end (1st mode of vibration), 𝑎₁/𝑊=0.0833, 𝑎₂/𝑊=0.166, 𝐿₁/𝐿=0.125, 𝐿₂/𝐿=0.4375. (b) Relative amplitude versus relative distance from the fixed end (2nd mode of vibration), 𝑎₁/𝑊=0.0833, 𝑎₂/𝑊=0.166, 𝐿₁/𝐿=0.125, 𝐿₂/𝐿=0.4375. (c) Relative amplitude versus relative distance from the fixed end (3rd mode of vibration), 𝑎₁/𝑊=0.0833, 𝑎₂/𝑊=0.166, 𝐿₁/𝐿=0.125, 𝐿₂/𝐿=0.4375.
